When a fluid flows through a sharp bend, low pressures may
develop in localized regions of the bend. Estimate the minimum
absolute pressure 1in psi2 that can develop without causing cavitation
if the fluid is water at
1.90 Estimate the minimum absolute pressure 1in pascals2 that can
be developed at the inlet of a pump to avoid cavitation if the fluid
is carbon tetrachloride at
1.91 When water at flows through a converging section of
pipe, the pressure decreases in the direction of flow. Estimate the
minimum absolute pressure that can develop without causing cavitation.
Express your answer in both BG and SI units.
1.92 At what atmospheric pressure will water boil at Express
your answer in both SI and BG units.
Section 1.9 Surface Tension
1.93 Obtain a photograph/image of a situation in which the surface
tension of a fluid is important. Print this photo and write a
brief paragraph that describes the situation involved.
1.94 When a 2-mm-diameter tube is inserted into a liquid in an
open tank, the liquid is observed to rise 10 mm above the free surface
of the liquid. The contact angle between the liquid and the tube
